ActiveX && Java

Question

Hi,
I try to embed Internet Explorer in my Java application via JNI.
I create child window via C++ code:
<=cut=>
HWND hWndChild = CreateWindow("AtlAxWin", "Shell.Explorer", WS_CHILD | WS_VISIBLE, x, y, cx, cy, hWndParent, NULL, hInst, NULL);
<=cut=>
Everything is ok, except that all java context windows, hints and top menu are hiding under browser.. Has anybody resolved such problem?
Thanks,
kostya.

Hi,
I'm afraid I don't have an answer for you, but I was hoping you could help me. I'm trying to embed IE in a java program, using the "http://www.nothome.com/IECanvas/" example that was suggested earlier. My main issue is that I have never done anything with JNI and was wondering if you could perhaps explain the following error message to me:
java.lang.UnsatisfiedLinkError: initialize
     at IECanvas.nothome.mswindows.IECanvas.initialize(Native Method)
     at IECanvas.nothome.mswindows.IECanvas.addNotify(IECanvas.java:63)

     at javax.swing.JComponent.addNotify(JComponent.java:3500)

     at java.awt.Component.setVisible(Component.java:903)
     at IECanvas.nothome.mswindows.IEBrowser.main(IEBrowser.java:142)
As far as I can tell this issue is with calling the "initialize" method. That code is below.
package nothome.mswindows;
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
import java.awt.peer.*;
import sun.awt.*;
import java.util.*;
public class IECanvas extends Canvas {
protected Vector listeners;
protected boolean useMozilla;
static {
System.loadLibrary("IECanvas");
// Native entry points.
public native void initialize(boolean useMozilla);
public native void sendurl(String strURL);
public native void resizeControl();
public native void gohome();
public native void rld();
public native void gofwd();
public native void gobackwd();
public native void setfocus();
public IECanvas() { this(false); }
public IECanvas(boolean useMozilla) {
listeners = new Vector();
this.useMozilla = useMozilla;
// Navigation methods
public void setURL(String urlString) {
sendurl(urlString);
public void goHome() { gohome(); }
public void reload() { rld(); }
public void goForward() { gofwd(); }
public void goBackward() { gobackwd(); }
// event notification
public void addIEEventListener(IEEventListener listener) {
listeners.add(listener);
public void removeIEEventListener(IEEventListener listener) {
listeners.remove(listener);
// We initialize the IECanvas on addNotify.
public void addNotify() {
super.addNotify();
System.out.println("using mozilla: " + useMozilla);
initialize(useMozilla);
public void setSize(int width, int height) {
super.setSize(width,height);
resizeControl();
public void setSize(Dimension d) {
super.setSize(d);
resizeControl();
public void setBounds(int x, int y, int width, int height) {
super.setBounds(x,y,width,height);
resizeControl();
I've left out the other methods, as they seem to deal with events once loaded, which is the state I'm trying to get to. My end goal is to get IE on a JPanel within my program (which is essentially a speciallized webbrowser). You're help would be greatly appreciated.
